Removed the existing propane water heater and installed a new 40-gallon Rheem power-vented water heater. The old tank was disconnected and removed, and new hot and cold water piping connections were installed. A thermostatic mixing valve was added and set to 120°F, and the water heater temperature was set to 140°F. All gas piping connections were leak tested and bubble tested, and no leaks are present at this time. An electrical outlet will need to be installed to supply power to the power vent unit. The tank has not yet been filled, and the gas supply to the unit remains shut off until power is provided and final startup can be completed.
